Specification of Letters Patent.

Patented Jan. 14,1908.

Application filed March 29.1904- Serial No. 200.511.

To all whom it may concern:

Be it known that I, TYRE C. HUGHES, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented new and useful 7, Improvements in Mixing-Machines, ofwhich the following is a specification.

Myinvention relates to improvements in mixing machines adapted to beused in mixing concrete, building or paving materials, wet or dry,plastic materials, such as'mortar, ore samples, or paints, dyes, oils orsimilar materials.

My invention is so constructed as to permit the discharge of the mixedmaterials during the feeding operation, thus rendering the operation ofthe machine practically continuous.

My invention provides further a mixing vessel having a single openingthrough which the materials to be mixed are both received anddischarged. Withsuch a construction the materials are discharged in anorder the reverse of that in which they are fed into the vessel, thuseffecting a much more thorough commingling of the different ingredientsthan is attained by machines in which the material is taken in to amixing vessel at one end and discharged at the opposite end thereof.

My invention provides further means by which one or more vessels,provided each witha sin le opening for receiving and discharging fhematerials to be mixed,'is revolved in two planes disposed at an angle toeach other, the vessels being disposed so that when one is receiving theother is discharging.

My invention also provides mixin blades 1 on the inner peripheries ofthe mixing vessels and disposed so that when the vessel is in thefeeding position, the blades will throw the material toward the closedend of the vessel in which the material is being fed, and also towardthe axis of the vessel, while in the vessel that is being discharged theblades will throw the material toward the opening as .well as toward theaxis.

My invention provides other novel features hereinafter fully describedand claimed.

In the accompanying drawings illustrating my invention, Figure 1 is 'atop view of the mixing machine, the propelling engine being omitted fromthe view. Fig. 2 1s a side elevation view. Fig. 3 is an end elevationview, showing the machine in position 7 for both feeding anddischarging. Fig. 4 is'a- 7 central verticalsectional view of the twovessels and parts connected therewith. Fig. 5 is a cross section takenon the dotted line ab in Fig. 4-, the supporting frame being omitted.Fig. 6 is a sectional detail view of a portion of the gearing employedfor revolving the vessels around their axes. a central longitudinalsectional view of the clutch mechanism. Fig. 8 is a cross section on theline cd of Fig. 1.

Similar characters of reference indicate similar parts.

1 denotes the base upon the upper side of;

which is mounted a boiler 2, engine 3, and three vertical bearings 1, 5and 6. The revoluble frame in which are mounted the mixing vesselscomprises two vertical gear wheels 7 and 8 connected by transverse bars9 and 10,. The wheels 7 and 8 are provided respectively with curved arms11 and 12, which are connected respectively by diametrical arms 13 and14, provided respectively with trunnions 15 and 16 rotatively mountedrespectively in the bearings 4 and 5. Rotation of the frame is providedby means of two pinions 17 and 18 mounted on and rotatable with ahorizontal shaft 19, the pinions meshing respectively with the gears 7and 8f Rotation of the shaft 19 is obtained in the manner hcreinafterdescribed. A shaft 20 located parallel with the gears 7 and 8 and in aplane coin cidental with the axes thereof, has its bearings inoppositely disposed bars 10. Two collars 21 on the shaft 20 disposed oneadjacent the inner side of each bar 10 are provided respectively withset screws 22 which engage t e shaft '20 and prevent endwise movement inthe bars 10 of the shaft 20.

The shaft 20 is disposed in the axis of a barrel or drum A, comprising atransverse member 23 consisting preferably of a large disk uniting twosmaller ends 33 and 34 of the barrel, and serving as a transversepartition for dividing the barrel into two chambers or vessels. Themember 23 is provided with peripheral teeth which engage a pinion 24secured upon a shaft 25 disposed parallel with shaft 20 and having itsends rotatively mounted in the'arms 12. The plate 23 is keyed to theshaft 20 so that the barrel A will rotate with said shaft. Secured onthe shaft 25 is a bevel gear wheel 26 which meshes with a bevel gearwheel 27 secured on and rotatable with a horizontal shaft 28, the endsof which are rotatively mounted in the bear- Fig. 7 is,

ing6 and in the hollow bore of the trunnion 16. On one end of the shaft28 is secured a disk 29 having a crank pin 30 to which is pivoted aconnecting rod 31, which is also connected in the usual manner to thepiston rod 32 of the engine 3.

The mixing vessels 33 and 34 are mainly cylindrical and converge atouter and opposite ends, the opposite ends of the vesse s 33 and 34having openings for receiving and discharging alternately the materialto be mixed. On the inner periphery of each vessel or chamber 33 and 34are provided a plurality of radially disposed mixing blades 35, whichwhen the barrel A is in one inclined position throws the material towardthe closed end of thb vessel that is uppermost, and toward the open endof the vessel that is lowermost.

A chute 36 is pivoted to a vertical post 37 which is provided with arest 38 for supporting the chute when the same is in position forfeeding. The dis osition of the chute 36 is such that, when t 1e vesselsare revolved with the frame in the direction of the movement of thehands of a clock, as shown in Fig. 3, the chute can be 'u tilted topermit the vessels to pass it. lVlnle in the feeding positionyas shownin Fig. 3, the chute will extend into the upper vessel 33.

The shaft 19 has its ends rotatively mounted in the bearings 4, and 6.Rotatable with and mounted on the shaft 19 is a clutch cone 39 which isslidable lengthwise on the shaft 19 and'is adapted to have one conicalend enter and clutch by friction a sprocket wheel 40 which is revoluble,when disengaged from the cone, upon the shaft 19.

From the above description it will be seen that the mixing barrel ordrum A is mounted for rotation around its own axis as well as around theaxis ofv the shaft and at right angles to its own axis. The firstmovement is continuous and the second movement capable of interruptionby means of the clutch 39. The first movement gives the principal mixing effect, and the second movement serves to, bring the barrel A intothe charging and discharging positions shown in Fig. 3. The charge to bemixed having been placed in the u per vessel of the inclined barrel A,the c utch 39, being at this time out of gear, is thrown in, and thebarrel or drum A at once begins to rotate clockwise, carrying thecharged compartment over trunnion 15 while continuing its rotationaround its own axis. I This rotation about trunnion 15 is continueduntil the charged compartment is brought into the discharging position,at which the other compartment is in the charging position. At this timethe clutch 39 is then thrown out and the series of events just describedis repeated, so as to charge, mix and discharge the other compartment.

Rotation is imparted to the s rocket Wheel by means of a sprocket chain41 which embraces also a sprocket wheel 42 mounted on and rotatable withthe shaft 28. To shift the cone 39 into or out of engagement with thesprocket wheel 40, a lever 43 pivoted to the bearing 6 is provided witha bifurcated lower end which engages an annular peripheral groove 44 inthe cone 39. By properly swinging the lever, the cone 39 may be made toengage the sprocket wheel 40 and .imparting thus rotation from the shaftl 28 to the shaft 19.

A more specific description of the operation of the parts is as follows:-The engine 3 is caused to rotate the shaft 28 by means of themechanism described, the lever 43 being positioned so that the cone 39will engage the sprocket wheel 40 and cause rotation to be imparted tothe shaft 19, by means of the chain 41 and sprocket wheel 42. Thepinions 17-and 18 rotating with the shaft 19 will impart rotation to theframe by means of the gears 7 and 8, thus swinging the vessels 33 and 34around in a plane perpendicular to the trunnions 15 and 16. When thevessel 33 and the vessel 34 are in the position inclined to thehorizontal, as shown in Fig. 3, the lever 43 is moved so as to releasethe cone 39irom the sprocket wheel 40, and the frame carrying the mixingvessels 33 and 34 will cease revolving. The material to be mixed maythen be poured into the upper vessel 33 through the chute 36. Duringthis time the shaft 28 in revolving revolves the vessels 33 and 34around their axes by means of the bevel gears 26 and 27 pinion 24 andtransverse plate or member 23. The material in the vessel 33 will bepicked up by the radial blades 35 and thrown toward the axis and theclosed end of the said vessel. When the vessel 33 is filled, the vessel34 will have been emptied, the blades 35 in the vessel 34 throwing thematerial toward the axis and the open end of the said vessel 34. Thelever 43 is then thrown so as to cause the rotation of the gears 7 and 8on the trunnions 15 and 16,

thus revolving the frame as already described and reversing thepositions of the vessels 33 and 34 from the positions shown in Fig. 3.At this time the vessel 34 will be receivin and the vessel 33discharging. The materia first entering the vessel will be the last tobe discharged, thus most thoroughly commingling the differentingredients that are being mixed. It will be noted that with the blades35 disposed radially, they will facilitate by their inclination from thehorizontal the discharge as well as entrance of the material. The timere uired for reversing the positions of the vesse s 33 and 34 beingcomparatively short, the operation of the machine will be practicallycontinuous.

If it is desired to use other means for driving the shaft 28 than thatshown, a pulley 45 is provided mounted on and rotatable with the shaft28. To this pulley a belt connected .frame supporting the vessels.

svasse with some suitable driving pulley may be connected. i

By maintaining the vessels in the position shown in Fig. 3, during thefeeding and discharging thereof, the inclination of the vesselsfacilitates the rapid movement of the ingredients within the vessels,and thus accomplishes with the aid of the rotary movement of the vesselsaround their axes, a more rapid and thorough comminglin of the materialsthan is attained with vesse s which are horizontally disposed duringrotation.

My invention is not confined in its scope to the particular means forrotating the vessels nor the exact means shown for rotating the Themovement of t ese parts may be obtained in other Ways than those shown.So also may the construction of the vessels be other than the formillustrated. Various other modifications of my invention may be resortedto without de arting from its spirit and scope.
